Description

The DI-2108-P Programmable High-Speed USB DAQ System from DATAQ Instruments.

Possible alternative product to the discontinued DI-155 model.

A basic High-Speed USB DAQ System is also available.

Product Features

  • 8 Analogue Input Channels
    Up to 8 Channels. Programmable ranges per channel are ±2.5, ±5, ±10, 0-5, 0-5 Volts.
  • Differential Analogue Input Configuration
    Enhanced noise immunity.
  • Synchronize Multiple Units
    Expand time-aligned channel count by adding more units. (Unlock code required per device)
  • Armoured Inputs Absorb Mistakes
    Analogue inputs are protected to ±150 V and digital inputs up to 25 V.
  • Fast, 160 kHz Sample Throughput Rate
  • 16-bit ADC Resolution
    Supports measurement sensitivity of up to 100 µV on its most sensitive, and 400 µV on its least sensitive range.
  • Stand-alone Data Logger Operation
    Store data to flash drives at throughput rates up to 160kHz.  (Unlock Code required to record all channels to USB thumb drive)
  • Pre/Post Tigger Storage to USB Memory
    Set trigger levels to record up to 2G (combined) of pre- and post trigger data (total file size of 4G).
  • Seven Digital Ports
    Folds discrete I/O into the measurements process. Each bit is programmable as an input or as a switch.
  • Rate Measurement Channel
    Measures pulse rate as may be acquired from a pickup for rpm measurement, or sensor to measure flow.
  • Counter Channel
    Tallies the number of pulses applied. Useful for integrating rate information, like flow rate to volume, or simply the number of definable events.
  • Software Support
    Supplied with ready-to-run WinDaq software, which records up to four channels at any sampling rate (purchase WinDaq/Unlock to record all channels, or to synchronize multiple units). Also provided with documented command protocol for OS-independent use.

 

Supplied with: a 6-foot USB cable, a screwdriver for signal connections, and a 32GB USB flash drive containing an NIST-traceable Calibration Certificate and WinDaq software.
